Rotary connector and fixing structure of rotary connector

Abstract

In a fixing structure of a rotary connector, which includes a projecting piece 15 to fix the rotary connector to a combination switch and a locked portion 22a to be locked by the projecting piece 15 and in which a laterally protruding locking claw 31 is formed in a tip portion of the projecting piece 15, the locking claw 31 of the projecting piece 15 is integrally provided with a flexible urging portion 15a that displaces and urges the locking claw 31 in a locking direction. A contact surface 32 is formed on the locking claw 31, the contact surface 32 obliquely coming into contact with a locking side corner 23 of the locked portion 22a from the opposing side.

The invention claimed is: 
     
       1. A rotary connector, comprising:
 a rotator; and 
 a stator supporting the rotator and having a projecting piece to be fixed to a combination switch, 
 wherein the projection piece includes a projection piece member integrally formed on the stator, and a locking claw member attached to a tip portion of the projecting piece member and comprising a locking claw and a flexible urging portion such that the flexible urging portion is configured to displace and urge the locking claw in a locking direction, and the locking claw member has a contact surface that obliquely comes into contact with a locked portion of the combination switch. 
 
     
     
       2. The rotary connector according to  claim 1 , wherein the contact surface is an inclined surface or a concave rounded surface. 
     
     
       3. The rotary connector according to  claim 1 , wherein the flexible urging portion is formed in a part closer to a base side than the locking claw in the projecting piece. 
     
     
       4. The rotary connector according to  claim 1 , wherein the contact surface is formed in a pair such that the pair of contact surfaces is formed laterally. 
     
     
       5. The rotary connector according to  claim 4 , wherein the flexible urging portion is formed in a section connecting the pair of contact surfaces. 
     
     
       6. The rotary connector according to  claim 5 , wherein the section connecting the pair of contact surfaces forms a tip of the projecting piece. 
     
     
       7. The rotary connector according to  claim 1 , wherein a protrusion that laterally protrudes most of the locking claw is continuously formed at an angle smaller than 180 degrees from the contact surface near a tip position in an insertion direction of the contact surface in the locking claw. 
     
     
       8. A fixing structure of a rotary connector, comprising:
 a projecting piece configured to fix a rotary connector to a combination switch; and 
 a locked portion configured to be locked by the projecting piece, 
 wherein the projection piece includes a projection piece member integrally formed on a stator, and a locking claw member attached to a tip portion of the projecting piece member and comprising a flexible urging portion such that the flexible urging portion is configured to displace and urge the locking claw in a locking direction, and the locking claw member has a contact surface that obliquely comes into contact with a locked portion of the combination switch. 
 
     
     
       9. The rotary connector according to  claim 2 , wherein the flexible urging portion is formed in a part closer to a base side than the locking claw in the projecting piece. 
     
     
       10. The rotary connector according to  claim 2 , wherein the contact surface is formed in a pair such that the pair of contact surfaces is formed laterally. 
     
     
       11. The rotary connector according to  claim 3 , wherein the contact surface is formed in a pair such that the pair of contact surfaces is formed laterally. 
     
     
       12. The rotary connector according to  claim 9 , wherein the contact surface is formed in a pair such that the pair of contact surfaces is formed laterally. 
     
     
       13. The rotary connector according to  claim 10 , wherein the flexible urging portion is formed in a section connecting the pair of contact surfaces. 
     
     
       14. The rotary connector according to  claim 11 , wherein the flexible urging portion is formed in a section connecting the pair of contact surfaces. 
     
     
       15. The rotary connector according to  claim 12 , wherein the flexible urging portion is formed in a section connecting the pair of contact surfaces. 
     
     
       16. The rotary connector according to  claim 13 , wherein the section connecting the pair of contact surfaces forms a tip of the projecting piece. 
     
     
       17. The rotary connector according to  claim 14 , wherein the section connecting the pair of contact surfaces forms a tip of the projecting piece. 
     
     
       18. The rotary connector according to  claim 15 , wherein the section connecting the pair of contact surfaces forms a tip of the projecting piece. 
     
     
       19. The rotary connector according to  claim 2 , wherein a protrusion that laterally protrudes most of the locking claw is continuously formed at an angle smaller than 180 degrees from the contact surface near a tip position in an insertion direction of the contact surface in the locking claw. 
     
     
       20. The rotary connector according to  claim 3 , wherein a protrusion that laterally protrudes most of the locking claw is continuously formed at an angle smaller than 180 degrees from the contact surface near a tip position in an insertion direction of the contact surface in the locking claw.
